How is carbon deposited on engine injectors formed? Professional technicians teach you how to prevent and clean up.

Hello, according to the question you asked, it is normal for the fuel injector to form carbon deposits, because there is a certain amount of gum in the fuel, which is easy to attach to the fuel injector and form carbon deposits after spark plug ignition and combustion, I am happy to answer for you!

The key to the fuel injector is that the carbons produced by gasoline combustion are deposited in places such as the fuel injector and throttle.

During the downward movement of the engine's power** piston, air or air-oil mixture is sucked into the cylinder, and then the piston moves upwards to compress the air-oil mixture into combustible gas, and finally the spark plug ignition detonates it. It can be seen that gasoline quality, air quality and engine combustion state are all factors affecting carbon deposition in fuel injectors.

Hello, the carbon deposit of the fuel injector has a lot to do with the quality of gasoline, which is slowly accumulated during operation.

Hello, this is due to the carbon emissions from gasoline combustion, which are deposited in the fuel injectors, throttle valves, etc., to form carbon deposits.

Riding a bicycle idling, gasoline combustion is incomplete.

The accumulation of carbon in the engine is like a swim and a smile.

Long-term idle operationWhen the diesel engine is idle for a long time, due to the low temperature in the cylinder and the insufficient fuel combustion, carbon deposits are easy to form on the combustion chamber and fuel injector, resulting in the deterioration of the working conditions of the fuel injector. This is especially true in cold winter climates. Due to the carbon deposition in the combustion chamber, the heat dissipation is slow, and in severe cases, the nozzle hole of the fuel injector will be blocked or the oil dripping phenomenon will occur.

The fuel is attached to the injector head for a long time and burns, and the resulting high temperature will cause the injector and the heat insulation sheath to burn. If the injection time is too late, the injection advance angle is too small, the fuel injection time will be too late, the fuel combustion situation will deteriorate, if the long-term adjustment is not made, the local high temperature will cause the fuel injector and heat insulation sheath to burn. The fuel is not clean, and there are small particles of impurities in the fuel, which will wear the needle valve and the needle valve body at the fuel injector, and the needle valve will be stuck in the needle valve body when it is serious.

The needle valve jam lags, and the fuel cannot be injected into the combustion chamber at the time, quantitative and rapid interval, and the phenomenon of oil dripping or injection will occur. At this time, the fuel atomization is not good, the combustion rate is reduced, and the combustion time at the fuel injector is prolonged, which eventually leads to the burning of the fuel injector and the heat insulation sheath. When this kind of failure occurs, there will be black smoke and shaking of the diesel engine.

If the heat insulation sheath of the fuel injector is not cleaned when it is not installed, there is a gap between the fuel injector head and the heat insulation sheath, the gas will enter the gap, resulting in the reduction of heat insulation and heat dissipation effect, and the fuel nozzle and heat insulation sheath will be burned. If the heat insulation sheath is installed too tightly, additional stress will be generated on the injector, and the combined effect of the heat alternating load and the high-pressure load of fuel injection will cause the injector head to break, and the needle valve will be stuck and drip. In addition, if the heat insulation sheath is omitted during maintenance, the fuel injector extends into the combustion chamber more than 4mm below the bottom of the cylinder head, which will increase the heat absorbed by the fuel injector and make the fuel injector melt.

Improper use of diesel engine: The lack of coolant in the operation of the diesel engine, and the high temperature caused by the lack of good cooling in the combustion chamber are also an important reason for the melting of the fuel injector.

Summary. The reason for the diesel engine burns the nozzle: The diesel engine burner is a troublesome situation, the burner should pay attention to its ignition, fast and slow, if the speed is not good, it is easy to burn the mouth, and this is the quality problem of this refueling, if the diesel quality is always not up to standard, it is possible that the oil added to the burner is not good, and the other gasoline of the whole family or too much may also burn the mouth.

The reason for the diesel engine to burn the nozzle: the vertical diesel engine light burner, this Yu Tan Kuan is, a more troublesome situation, close the burner should pay attention to its ignition, fast and slow, if the speed is not good, easy to burn the mouth, and this is the quality of this refueling, if the diesel quality is always not up to standard, it is possible that the oil added to the burner is not good, and the other gasoline of the whole family is too much may also burn the mouthpiece.

There are several reasons for this situation: 1. The diesel filter is damaged and the diesel is too dirty. 2. The top bead of the oil needle in the injector sinks too much, and it is best to change the fuel injection and laugher assembly, because the market cannot buy qualified oil needles.

3. The injector gasket leaks and rolls against the air, which will overheat the injector and burn out the nozzle.

Summary. Hello, I am glad to serve you, here for you to find out the reasons for the diesel engine to burn the nozzle: 1. The grease nozzle is blocked

Because the oil hole in the grease nozzle is blocked by dirt, grease and other substances, the grease nozzle cannot pass through the grease nozzle normally, resulting in oil burning on the grease nozzle. 2. Mismatch of the oil nozzle: the model of the diesel engine oil nozzle and the model of the fuel injector do not match, resulting in the oil burning of the oil nozzle.

3. Aging of the grease nozzle: The grease nozzle of the diesel engine will age when it is often used, which will make the grease nozzle unable to work normally, resulting in the oil burning of the oil nozzle. 4. Insufficient oil pressure

Insufficient oil pressure in a diesel engine will cause the nozzle to not work properly, and it will also cause the nozzle to burn oil.

Hello, I am very happy to serve you, here for you to find out the reasons for the diesel engine to burn the nozzle: 1. The grease nozzle is blocked: because the oil hole in the grease nozzle is blocked by dirt, grease and other substances, so that the grease nozzle can not normally know that the dust passes through the oil nozzle, resulting in the oil burning of the oil nozzle.

2. Mismatch of the oil nozzle: the model of the diesel engine oil nozzle and the model of the fuel injector do not match, resulting in the oil burning of the oil nozzle. 3. Aging of grease nozzle:

The oil nozzle of the diesel engine will be aged when it is often used, which will make the oil nozzle unable to work normally, resulting in the oil burning of the oil nipple. 4. Insufficient oil pressure: The insufficient oil pressure of the diesel engine will cause the oil nozzle to work properly, and it will also cause the oil nozzle to burn.

Danbu. The disadvantages of diesel engine fuel nozzle burning are: 1. The wear of the trouser burner nozzle will affect the sexual impulse and quiet energy of the engine, poor combustion, increased fuel consumption, and more pollutants are emitted. 2. The wear of the burner nozzle will affect the engine stability of the engine, increase the engine vibration, and reduce the engine life.

3. The wear of the fuel nozzle will affect the injection of fuel, and the injection will be uneven, which will affect the power performance of the engine. 4. The wear of the fuel nozzle will affect the power performance of the engine, the engine power will decrease, the fuel consumption will increase, and the acceleration performance will decrease.

Summary. There are several reasons for this condition: 1. The diesel filter is damaged and the diesel is too dirty.

2. There are too many sags in the top bead of the oil needle in the injector, and it is best to change the injector assembly at this time, because there is no qualified oil needle on the market. 3. The injector gasket is leaking, which will overheat the injector and burn out the nozzle.

The reason for the diesel hair filial piety motive burning nozzle: dear, hello! Glad for your question!

There are several reasons for this: 1. The diesel filter is damaged and the diesel is too dirty. 2. The top bead of the oil needle in the injector sinks too much, and it is best to change the injector assembly at this time, because the oil needle in the market cannot be bought with this vertical argument.

3. The injector gasket is leaking, which will overheat the injector and burn out the nozzle.

A 10-horsepower diesel engine burns one in its mouth for a period of time.

There are several reasons for this condition: 1. The diesel filter is damaged and the diesel is too dirty. There are too many oil needles in the injector in the 2 injectors, so it is best to change the injector assembly, because the market can not buy a qualified oil needle.

3. The injector gasket is leaking, which will make the injector overheat and burn the nozzle.

Diesel engine fuel injector carbon deposition what to deal with, first, no matter how good the gasoline is, it is impossible to achieve 100% combustion, and it will more or less generate sediment carbon deposits. Carbon deposits are harmless and do no good, and if there is carbon deposits, they need to be removed. Second, the method of removing carbon deposits is divided into dismantling and dismantling removal, among which, the purpose of dismantling and cleaning can be achieved by adding fuel cleaning agent.

3. The general cleaning agent is used once in 2000-5000 kilometers, and the functions of each product are different, please understand its product instructions in detail before purchasing. Therefore, it is very necessary to use fuel additives on a regular basis! As for the brand, as long as the quality is passed, you can choose the one before the big choice!
